To all (za/om 'it m09/ concern.:

13e-fit known that LHnNnY iV. B. GRAHAM, a citizen of the United States, residing at New London, 'in the, county of Huron and State 'of liiohave invented certain new and nseful Improvements 'in and Relating to Brick Machines. of which the following is a specitic'ation. y y i My invention relates to lbrick making apparatus. Itmay be and preferably is embodied inthttypeof appa-ratiis wherein a plnrality of'i'nolds are successively filled and emptied. d

`The invention particularly relates to and comprises improvements upon or in apparatus .onf the character disclosed in my co-i'iending application Ser. No.`81,1l25.

,One object of the invention `is to simplify and improve the 'mechanism disclosed in my aforesaid application for separating the molds and bricks, `for discharging and for handling the empty molds, whereby the con-- struction is materially cheapened, the molds positively guided and manipulated, the distance ot travel of the molds shortened, nndne strains on the molds and machine minimized and the oiitpnt of the machine materially increased. A

-Another object ofthe invention is to provide novel mechanism adapted to invert filled molds, separate they molds from the lnicks and to quickly discharge the empty molds.

A further object oftheinvention isto provide novel mechanism adapted to invert filled molds, separate the molds from the bricks and to turn the empty molds right side up.

Anotherfobject o't' the invention is to provide improved mechanism which inverts and siibstantially simultaneously separates the molds'aiid bricks and then discharges and also positions the empty molds right side up for delivery to thesanding mechanism or retn'i'n to their 'feed-ing position.

The member 25a' preferably comprises three elements. to-\vit: (ll an element ill adapted to receive and support a pallet lll (Fig. lill, which in turn receives and supports the bricks dumped from the mold as ther latter inverted (Fig. itil; (2l a separator element 32 which entrati-esv the end Walls or members ot the mold 11i to cause separation of the mold 'from the brit and Which linally discharges the enrol.)y mold, and an element Which receives the empty mold from 'the separator element 32 (Fig-s. 12 and 13) and rights the .mld and then positions it on the chiite 14C). The element 33 is. by prof connected to the element 31 and mores with, but is so arranged reletre to the ment 31 about the axis or the a( shaft 25", that it occupies aposition b 'tween the members 25a, 25M, nd belowY or opening 25K between thema when ine-mn bers are operated 'to the'open position, ./ill of the elements just referred to (er-:cept certain parts oil the separator element mt to he`d escribed) are icifiedly connected o the adjacent roclr shaft tor bodily increment therewith. The pallet and hriclr receiving: element 551 preferably comprises a pair or castings harina` hubs Ela which may he split and clamped in any desired ivi yes by boli 31b-to the shaft and arms The arms El may be connected together by i angle iron 31d, the opstanding leef ot Winch serves to support the p .llet 14 movement inwardly or downwardly the arms 31 move upwardly and downwardly. l,fach arm may le provided with a 'toot fll" on which the mold rocks it 10's past the vertical from the member Q5 to the member 25a (see Figs. 14 and l5).v By prete-rence the element 33 may comprise pair ci? 38, each ot which connected to one et arms 31. as shown in Fig. il.. thif nr rangement, the arms swin donfnwaro and rearwardly. the arms 31 so ,1, Wardly, and carry the empty mold with them until it is slightly re-inyerted or turned. right side up.. after which and While the arms are still merino; rearwardly.v the oppor side of the mold Will oravitote downwardly so that the mold finally is completely righted and then positioned or discharged on the chute `Each arm is provided with fi toet piece on which the mold 1d: rests and pivots as the element 33 sii/'ings downwardly and rearwardly to its rearmost position Figs. 14- and The separator elem-9 f preferably comprises a pair arranged on the adjacent she. y of the t rms 31"'q so as to engage the mol d le yond the opposite ence of the prllet Each device is prom/:led i'ith a mold en :ringing VmemberN indicated at 5352/2 which is arrested in the opening); movement ol' the ments 31 and 3Q. to conse separotim'i et lhs mold Jfrom thehrielrs the element Ill mores to its extreme open position. The mold gagging members 32" and their operation will be later referred to.

To permit and insure ready oniel: delivery otthe empty mold from the separat` devices to the receivine and discharge element 33,caoh ot these sepa-rating devices is preferably formed oit two members 32, 32@ one ot which (3m) is inov able relatire to the other (32), whereby it and the adjacent mold engagingmember 32d, which engages andsupports each mold, may be stop ed at a predetermined inclined position to eteot delivery of the mold to the discharge element For this purpose each member 32h is fixed to and moves With. the adjacent'shaft Q5 and 1the adjacent member $12 is preiierably loosely mounted on the adjacent shaft 25C, whereby it may be arrested or stopped at a predetermined position during.; movement of the lined member 32". The ieiold engaging.members 32d are inovably mounted on the elements 82C and move relative thereto in the manner hereinafter described as the swingable member 25a swings to the open position to separate the mold from the hricls (see Fig. 16). At or near its outer end each element 32 is formed with a socket or guide Walls 32C', in Which i.. slidably supported a rod or leg 32e depending from the adjaent member 32d. The rod 32e is of proper shape in cross section to properly lit and more endwiee in the socket B2C', The mold engaging; iioeinbers are preferably provided With rollers 39j which permit thc molds 143; to readily slide voli: thereof, and stops which prevent the inolds Afrom railing; or rolling; ofi1 the members 32d in outward direction as they swing to the open position.

1nich member 32C is preferably held in hired relationship With the adjacent member 32D dnriin portion ot its movei'nent by the instrinnentalities: 34 indicates a rod piiotally connected at its outer end in any rell known manner upon a stud 34 proyec LV; from the member 32 (see Figs. 5 and i The rod etends throuffh indicates a compression sprinof inter nosed il 1'? between the collar 35 and member 39]. In

assembling; these elements the nut is adjusted to place the 36 under soilioient comp; so that it may act on the collar and.x through it and the rod 36. 'tunes tion to hold the adUz/cent member 32 yieldthe member 32h., or by prei?- More. en adjustable stop 37 carried there` by. whereby they may swing' together as a nuit dnrine the operation ot the swingable :penal 25an until the loosely mounted member 22C enges; a stop 38. which enviroment talres place during the latter part or the movement ot the member 25" in the op ,ning direction and after the mold and hr' have been separated from each other (lli 17). .es the lmember 25a Swings to the rull open `positionn the members BQ, Will engage the fixed stops 3S `and be held against `further swinging movement with the mem ber 32', but the members 32 will continue to more to their' extreme open position thus placing the springftj under compression (see Figs. 1T and 18) rllie stops Zitareso arranged that at the time the members 2&2 are engaged and arrested thereby, the latter will be in a predetermined inclined position, thus insuring that the empty mold on the mold engaging members 32d will, under the influence of gravity. quickly roll or slide oli rearwardly on t-o thel discharge member 33. iHowever, it may be explained at this point that engagement ot' the members 252C with the stops 3S does not take place until the bricks are separated Jfrom the empty mold lei, asl it is essential during the travel of the devices 32 toward the opening position, while dumping and separation of the bricks is `taking place. that the pallet be maintained parallel with the mold and that their relative movement'be per iendirular. Due to the fact that the operating connections 46 are constructed and arranged to move the element 3l to a downwardly inclined position (see Fig. 1T), the pallet 1 4 and bricks thereon may be discharged upon or .caused to engage a'suitable conveyor 5l,

preferably ot the gravity type. whereby they will readily move away trom the apparatus. My construction lends itself admirably to the accomplishing or these results. Each stop Btl may comprise a screw adjustably mounted in an opening formed in a bracket SSeQwhich is tixedto and depends from the adjacent-'arm 27. is shown in Figs. (3, 9 and 12, the free end of each arm 27 is bent downwardlyand the bracket 38a is secured to said end by bolts 38h. Each stop BS may be maintained in its adjusted position by a nut 38C. or other locking means.

49. 49, indicate a pair ot arresters which engage the mold engaging members 32d as the latter swing to the open position with the devices 32h, 82e, and arms 3P. Each arrester is preferably pivoted at its lower` end in" bearings 419a provided on a. suitable bracket 50. The bracket 50 may be secured in any desired manner, preferably by the bolts 38h, to the depending end ot' the ad- ]acent supporting arm QTC (Figs. 9 and 110).

The `arrester 49 is pivoted to swing 'forwardly and rearwardly (see dotted lines in Fig. 9), to accommodate itselt to the positions of the mold engaging members 32d as the member 25a swings in either direction. 50 indicates astop or abutment provided on the wall of the bearing 49a. This stop is arranged in the patlrotl movement oli' a lug` 50" provided on the hub or' the arrester and serves to limit the movement thereot in one direction. The stop `50 is preferably arranged to support the arrester in normal position or that position wherein it may en member hub ot the arrester 49, one ot its arms being.

lconnected to the bracket 50 and its other arm being Yformed with a loop that surrounds a` bolt 50" on the arrester (see Fig. 9).

Each arrester preferably comprises a hub member t9 and a leg 49" adjustably secured together by a l lt ibi The upper end of the leg eltlx is preferably biturcated, whereby it may readily be engaged by the pin or roller 4S". Y'ly adjusting the leg` 419x relative to the hub member 49, the upper end of the arrester can be properly positioned.

52 indicates shoes which operate to support and guide each mold as it moves irom the separating1 members 32 to the discharge 33. The shoes 52 are preferably supported by the members 32"; this arrangement brings the shoes in line with the ends or end walls ot the molds Lt. The shoes serve to elevate the rear edge of the mold as it moves on to the arms 3 as shown in Fig. 12. B y this arrangement the mold has sliding Contact with tbe arms :33 at its trent edge only, hence all danger o'i the mold sticking to the arms 33 due to any wet clay thereon is eliminated. l

The conveyor 51 operates to convey away the dumped bricks and the pallets, on whic i they rest, trom the inverting, separating and discharge mechanism 25. The conveyor 5l may comprise a pair of bars 5l on which are loosely mounted rollers 5l. The inner lree ends or the bars 5l are preferably connected to a pair oil" collars 5l, loosely mountw ed on the adjacent shatt 25C. The collars 5lC are preferably provided with grease cups 5Fl. The collars 5l serve` as a connection between the conveyor and shaft 25, whereby the latter may support the adjacent end ot` the conveyor and maintain it in proper corrclationship to the arms 3l. The inner end of the conveyor 5l extends to a position between thc arms 3l" and is preferably disposed in plane substantially parallel to but slightly above that in which the arms are positioned when at the end ot their movement to the open position (see 3, 6 and 17). By this arrangement, the conveyor intercepts each lallet and the bricks thereon as the member 25u swings lto the open position and permits the pallet and bricks to gravii tate away `from the arms 31C (see Figs. El and 1T) and move to a place ot storage or treat- 11u-at.` The operating connections tor the members 251, Q51". which will presently be described. are so constructed and timed that the pallet and bricks thereon will have lll) lill) lill) moved out of the paths of movement of the arms 3l, before the latter reach the plane of the conveyor in their return upward movement.

46 indicates as an entirety the mechanism for operating the shafts 25C. As the shafts 25c are geared together at one end by the gears 28, as already described, the mechanism is connected through a crank arm 46a with but one of said shafts. The'hub 46 of the arm 46 may be xed to the extended end oi the adjacent shaft 25c by a set screw 466x, The mechanism 46 is operatively connected by a crank or crank pin with one of the operating shafts of the apparatus. By preference the mechanism is connected to a rocker 42h pivoted at 42c upon the adjacent trame member ll; which rocker may in turn be connected by the elements about to be referredto with a crank pin 42 fixed to a pinion 40c on the extended end ot the shaft 401. The pinion 40C meshes with a gear 54c which is connected to the shaft 54" of the sanding mechanism 54. 42a indicates a rod or pitman connected at one end to the crank pin 42. The opposite end of the rod 42`^L is pivotally connected on a pin 42" which may be adjustably connected to the rocker 42b in any desired manner; for instance, the pin 42M may extend through a slot 42" formed 1n the rocker and be adjustably secured or clamped to the walls of the slot in any desired manner.

The elements of the mechanism 46 preferably include relatively movable members connected by suitable springs, as will be later set forth. The purposes or this construction is to provide suitable rest periods between successive operations of the swingable members 25, 25a', during Ieach of which periods a filled mold 14 is delivered to the receiving member 25a and an empty mold and a pallet with bricks thereon are permitted to move off of the members 32d, 3l, respectively, as well as to reduce strains and stresses on the elements of the operating connections and inverting and i separating mechanism 25. Furthermore, the rate ot movement or speed oi' the members 25a, 25a', in their movement toward each other', may be maintained up to any predetermined point, which point may be fixed by the interpositioning ot a stoppage means, so that enough momentum will be imparted to the mold to cause it to swing over the vertical trom the member 25a to the member 25a. Again, by this construction I am enabled to (l) move the swingable members towards each other and up to a prede termined point, (2) maintain them in that position while the mold swings from the member 25il to the memberl 25M, and prevent them from falling` backwards until the operating connections 46 change their direction of movement and start to operate in the opposite direction.

Of the operatingmechanism 46, 46'J indicates a rod pivotally connected at its rear end in any desired manner to the rocker 42h. The rod 46b preferably telescopes in and partially extends through a member 46, and carries near its inner end a pair of adjustable collars 47, 47X, each of which may be adjustably lined to the rod by set screws 47. The member 46c may comprise a pair of blocks 47a, 47 b, and a pair of strips 47 c, which conneet the blocks together and form guides for the collars 47, 47", and through them guide the rod 46. The block 47b is formed with an opening through which the rod 46b slides. The rod 46b is preferably formed ot two elements 46V, 46h, (Fig. 8) connected together by screw threads, whereby the rod may be readily lengthened or shortened. The block 47a is pivotally connected to the crank 46a in any suitable manner. Preferably, the crank 46a is provided with an elongated slot 47 d (see Fig. 8) through which the pivot pin 46a or" the connection extends, to permit adjustment of the pin toward and from the axis ot' the shaft 25C. The pivot pin 46a may comprise a bolt adapted to take a nut whereby it may be secured to the crank. 46, 461, indicate compression springs preferably coiled around the rod 46h, the spring 46i being interposed between the collar 47 and the block 47l and the spring 46d being inter-` posed between the block 47x and the block 47 b. The springs 46d, 46d', being coiled around the rod 46h, are maintained in proper position at all times. stood, the spring 46d is compressed in the` forward stroke of the rod 46b and when the compression is great enough to overcome the resistance of the members 25a, 25a', the rod 46", through the spring, operates the crank arm 46a and it in turn swings the members 25, 25, upwardly or toward each other; likewise in the return stroke of the rod 46", the spring 46d is relieved and the spring 46d is compressed and when the compression is` great enough, the rod 46", through the spring 46d', operates the crank arm in the opposite direction. This construction and arran ement permits relative movement between t e rod 46b and telescopic member 46c after the crank 46a has been moved to its rearmost and forwardmost positions. Accordingly, (l) a period or' rest is provided for the members 25u, 25a', while in their open position during the time the rod 46b is moving rearwardly (after the crank 46 reaches its rearmost position) and then forwardly until it commences to compress the spring 46d, and (2) after the crank 46a reaches its forwardmost position, which is preferably determined by a stop 43 to be later described, the spring 46cl operates to maintain the members 25, 25a, substantially together (see Fig. 15) during the time the rod 46l continues to move forwardly and then rearwardly until it com As will be undermencesto compress the spring 46d. The rest period provided tor the members 25, 25M, as just described, is ot sutiicient length to permit the mold push-out 23 to deliver the forwardmost mold tl onto the swingable member 25a, and to permit an en'ipty mold lll to slide trom the members 32 onto the discharge member 33 and a pallet let ot bricks to gravitate or roll on the conveyor l. out of the path ot movement oit the arms 31C.

The stop t3 is preterably carried by one oit the shafts and 1s arranged to engage some adjacent part of the machine (see Fig. 8) to stop the members 25, 25a', in their npward movement in a predetermined position (see Fig. l5) due to the operation of the connections 46 forwardly, as already described. rl`he stop fl?) extends laterally from a sleeve l and overlies the adjacent shaft bearing box (see Fig. l), so as to engage therewith to limit the movement of the shatt in one direction-the direction ot niovenient to close the swingable members 25H, 25M. The sleeve 43 is preferably adjustably connected to the adjacent shaft 25 by a clamping bolt lil, By proper adjustment ott the stop -l-, the operation of the members 25, 25. can be proprely controlled. r#L69 and Gf indicate guards carried by the member d6" arranged to prevent any particles or lumps ot' clay falling on certain elements ot' the operating mechin nism #lo and affecting their operation.

sl-l indicates a pair of guides arranged at opposite sides ot the support 22 and proliet-ting 'from the 'free or 'lorward end thereof. The guide walls are inclined toward each other and serve to engage either end or end wall ol a mold 'll and move it transversely o'tI the support, as the mold is moved *forward to arrange it centrally ot the support and in position to be received, inverted, dumped and discharged by the inverting, separating and discharge mechanism Each ot' the guides #tel may be supported by a pair ot .diei el strips del, el@ fixed to some stationary part or parts ot the machine.

ll" indicates a transverse sha'tt mounted at its opposite ends in suitable bearings 3l preferably provided in the blocks il. 3l indicates a gear lined to the shaft 31X and arranged to mesh with and be driven b v a gear 2h. 80 indicates a roel: sha't preferably mounted at its opposite ends in suitable supports or bearings SO secured to the flanges ot' the sills l. and adapted to pivotallv sup port the rocker ill). The rocker preterably secured to the shatt SO by set screws Sol. (lne tace oi the rocker Bl) is formed with an elongated chamber 530% the side walls ot which operate as guides iior a blocl 20, 210C indicates a crank nin secured to the inner tace oit' the gear Si. The crank pin 30" efrtends into a bearing 30" provided in the block 30". It Will be understood that when lation ol elements, which are disclosed for illustratrve purposes, "r'or ope ating the pit man 25), the rocker 3l) is disposed between the bearings 3l ilor the shaft 531x; accordingly, l provide the rocker BO with an elongated, curved slot 30 through which the shaft 31x extends. This slot permits the rocker to be operated, as above described. Since the bloei; Bill) slides across the slot 30 when the rocker is at its exreme positions olf movement tornardly and reaiwvardly, no interference thereoll with the shaft 3l can occur. as will be Vtally understood Vtroni Figs. 29, 30, 3l and 3;?. i

To insure proper correlation between the elements oi the mechanisms driven by or troni the shalt 2g and those elements oi thrl mechanisms driven4 from the shat't I preler to provide between the shaft and the gear l an adjustable connection 8l, more clearly .shown in Figs. 33, 3ft and 85. Ot 'these connections Sl indicates a collar keyed to the sha tt 2t. The collar has an arm Sib Formed with a plurality of openings 81". The web ol' the gear 2f is provided with an integral plate in which are itormcd a plurality et openings di, any one oi which muv be brought into registry with one of the openings 8l. S3 indicates a clamping bolt u hi=h extends through one oit the openings fl and the opening S2 brought into registry therewith and by means oi a nut S3 si cure the gear 2f to the arm 81h.

(lperation: is shown in the drawings mv :niparatus constructed to operate upon a plurality et molds which successivelj.Y .move troni one position to another so that they are lilled and emptied, then sanded and returned to position for refilling. titarting with a mold Alei; on the receiver 2l. it is engaged b v the puslrout 253 and moved to the filling station. llpon the return ot the push-out. another n'iold let is positioned on the receiver 2l and it is engaged bv the push-out E233 and moved to lilling station. The .second mold engages the tiret iuold and pushes it Yiorward ou the support 2Q. Through this` operatimi eat-h mold is posi tioned Vlor bumpingl by the bumping mechanism 2l and delivered to the inverting. separating and discharge mechanism 05. The operation of the push-out 2?) and swingablo members "Vrh 25 are correlated,so that the deliverv oic a illed mold to the member Q5 takes place when said members are in their open position (see lliu 3 and l2). lllhile in this open position, a pallet let is llt) placed on the arms 31C. Upon the delivery o1"- a mold to the member 25, both members 25, 25, swing' toward each other (see Figs. 13 and lll), the lower edge or the mold engages the feet 231C" oit the arms 3l@ and rocks thereon, the mold swings past the vertical, onto the n: n'iber 25M (see Fig. due to the n'ionientum imparted to it by the upward swing ot the member 25, thereupon` the members 25, 25a", swin in .the opposite direction (Figi lo) or to the open position (Fig, 17). During this movement (l.) the arresters Il@ engage the rollers 419i and arrest the mold engaging members 32 (F lo), thus causing,` separation of the mold 'from the bricks which continue moving or gravitating downwardly with the` pallet llt and the arms 31C; and following the separation of the mold from the bricks, the n'iembers 82 engage the stops 38. These stops are so arranged that when the members 32C engage therewith, the mold engaging members 32d, which are carried by the members 32, will be inclined downwardly and rearwardly. is a result o't this disposition of the members 32, the empty mold will `slide rearwardly and gravitate downwardly (Fig. i7) between the members 25, 25a, onto the discharge element 33 whichV has moved into position to receive the empty mold. is the arms 231C continue moving to their extreme open position, the pallet 14 engages the conveyor 5l and then gravitates thereon 17); at or about the same time, the puslrout 253 delivers a filled mold to the member 25e. The members 25, 25a', then swing toward each other and the operation just described .is repeated. is the members 25', 25a', swine; toward each other, the arms 33 swing` di wnwardly and rearwardly 13 and la) so that one filled mold is being' inverted, already set forth, the previously emptied mold is turned right side up and discharged or positioned on the conveyor 53 (Fig. 14;).
